GC problems sometimes result from the wrong __init_Foo being passed to
startupHaskell. The symbol you pass in must relate to the topmost
module in your program; all other modules must be directly or indirectly
imported by the topmost module.
If you're sure this is the case, could you send me the code and I'll
take a look.
Cheers,
Simon
